Patent EP-0399138-A3 (EP)
IPC: H05K13/00
Filed: 1990-02-05
Abstract: Since, with increasing miniaturisation of the structures on printed-circuit boards, the width of the conductor tracks is approaching the conductor track height, ever higher demands are being placed on the testing of such printed-circuit boards. The presently existing disadvantages such as, for example, too low a height resolution, low processing speed or difficulty in manipulation are eliminated by means of the method according to the invention for testing in the microscopic and macroscopic range of a printed- conductor board, as well as of a corresponding arrangement. Testing in the microscopic range is performed in each case inside unchanging, displaceable evaluation windows (20) by calculating cross-sectional areas (18, 19) at each scanned point on the printed-circuit board. Macroscopic testing is performed by calculating specific simple geometrical magnitudes inside grid coordinate systems (16, 17), followed by comparison with a reference. The arrangement for executing the method consists of a laser scanner for triangulation, an evaluation unit (9) and at least one high-resolution, position- sensitive detector (8).

Patent EP-0402738-A3 (EP)
IPC: H01M4/80
Filed: 1990-06-05
Abstract: The invention provides a nickel foam and a method of forming a nickel foam for a nickel containing battery. An open-cell foam structure is placed in a nickel carbonyl gas containing structure. The foam structure is heated to a temperature at which nickel carbonyl decomposes. Nickel from the nickel carbonyl gas decomposes on the foam structure to form a nickel plated foam structure. The nickel plated foam structure is then sintered leaving an open-cell nickel network to form the nickel foam. The open-cells of the nickel foam comprise substantially hollow nickel wires having a substantially uniform transverse cross-section. The nickel foam is further characterized by the conductivity through the nickel foam multiplied by a factor of 3.4 being equal to or greater than the theoretical conductivity of nickel.

Title: Calibration of a cartridge handling device using mechanical sense of touch
IPC: G11B17/22
Filed: 1990-03-20
Abstract: Disclosed is an optical disk handling system (24), called an 
autochanger, having two control systems (150Y, 150Z) to provide the 
six motions necessary to move optical disk cartridges from storage 
holding cells to an optical drive. The system uses shaft encoders 
(62, 72) on two motors (60, 70) of the two control systems, and 
current or voltage feedback from the motors, for all positioning 
of the mechanisms controlled by the two control systems. This 
positioning includes initial calibration as well as detecting the 
location of the mechanisms during, and at the end of, moves. The 
shaft encoders (62, 72) are used to position a mechanism close to 
the eventual move location, then motor current or voltage feedback 
is used to determine the opposition to the movement of the 
mechanism, which tells the control system whether the mechanism has 
reached its destination. The control systems use a flip mechanism 
(49) in the autochanger to turn the cartridge over, allowing either 
side of the disk to be arranged for reading or writing by the 
optical drive. The control systems use a lateral displacement 
mechanism (51) to move a cartridge from a cell in one of the two 
columns of the autochanger to a cell in the other column, or to 
move a cartridge between the optical drive, which is located in one 
of the columns, to a cell in the other column. The control systems 
use a cartridge engaging mechanism (45) to attach to an exposed end 
portion of a cartridge positioned in a cell or the optical drive. 
A longitudinal displacement mechanism (47) is used by the control 
systems to move the cartridge, after attachment, out of the cell 
 
 
or optical drive. After positioning the cartridge vertically and 
laterally, the longitudinal displacement mechanism (47) is then 
used to move the cartridge into a cell or the optical drive, where 
the engaging mechanism (45) releases the cartridge. An important 
aspect of the invention is that the longitudinal displacement 
mechanism (47), the flip mechanism (49), the lateral displacement 
mechanism (51), the engagement mechanism (45), and the mailslot 
mechanism (41) are operated by one of the two control systems. The 
other of the two control systems is used for vertical displacement 
of the cartridge. During initialization of the cartridge handling 
system, it uses the shaft encoders (62, 72), along with current or 
voltage feedback from the motors, to calibrate the home locations 
of the mechanisms. The system determines the home position for 
vertical movement of the transport as well as the top and bottom 
positions used for the translate operation. The system then 
calibrates the plunge movement, the flip movement, and the 
translate movement. Finally, the system determines whether the 
path for all the movements is free of obstructions.

width of the mold slit corresponding to the minimum 
value of the roughness of the embossment formed on the 
surface of said thermoplastic resin sheets, whereby 
defects such as the adhesion to and winding on to 
rollers, inferior appearance and sizing marks which are 
prone to occur when the sheets are embossed with 
embossing rollers may be eliminated.

Title: Method of predicting cell-to-cell hand-offs for a satellite cellular communications system
IPC: H04W64/00
Filed: 1990-10-01
Abstract: A method of predicting cell-to-cell hand-offs of mobile subscribers (22) for a satellite cellular communications system. Each satellite (10) of a constellation projects a number of beams or cells (20,26) upon the earth for communication with mobile subscribers. The satellite (10) transfers (hand-offs) communications links from cell to cell as the satellite moves over the mobile subscriber. Since the movement of the satellite is stabilized in three directions, the projection of the beams or cells (24,26,28) follows a predictable path across the face of the earth. Each satellite moves across the earth in one direction. Once a subscriber is located within one cell (24), the next cell (26) to which the mobile subscriber is handed-off may be determined from the geographic position. For mobile users which are close to boundaries between cells, additional position location may be determined by the calculation of bit error rates (50-68). The results of these bit error rate measurements then indicate the identity of the cell which is to receive the hand-off of the mobile user.

Patent EP-0397620-A3 (EP)
IPC: E06B9/60
Filed: 1990-05-08
Abstract: This device comprises a roller (1) on which the curtain 
is rolled up, and which has its ends closed by a washer 
(3) and a cap (2), provided with two opposed recesses 
(5,6), one inside and the other outside the roller.  
     A first support means (9) is inserted in the outer 
recess (6) and supports the end of a threaded rod (14) 
passing inside the roller to be inserted, with its 
other end, in a second support (16) fastened to the 
washer (3). The threaded rod crosses two opposed bodies 
(17,18), one of which is fixed and the other is movable, 
by virtue of its coupling with the threaded rod and its 
axial rotation.  
     Between the two bodies (17,18), a helical spring (19) is 
interposed, having its ends fastened to the same bodies. 
The rotation of the roller causes the rotation of the 
movable body, which twists the spring, but at the same 
time moves along the threaded rod, so increasing the 
longitudinal space available to the same spring (19).
